WATER-PUBIIFYING AND LIICE APPARATUS.

To all whom it may concern:

Be it known that I, ADOLPHE LEwIs HEL- WIG, a citizen of the United States, and a resident of Paris, France, whose post-office address is 1 Rue de Laborde, Paris, France, have invented a new and useful Improvement in VVater-Purifying and Like Apparatus, for which I have obtained a patent in Belgium, No. 194,762, dated September 8, 1906 and I hereby declare the following specification, taken in connection with the accompanying drawings, to be a full, clear, and exact description of the same.

My invention relates to an improvement in a measuring apparatus for treating water by means of chemical products with the object of freeing it from the impurities which it contains in solution or in suspension. The object of my invention is to automatically measure out and add to the water, in a simple and efiicient manner, and in roportion to the quantity of the water an its degree of impurity, the chemical substances with which it is to be treated.

In the annexed drawings which show by way of example a practical form of the apparatus according to this invention, Figure 1 is an elevation of the apparatus in vertical longitudinal section on the line 1-1 of Fig. 2, as arranged over a filter or settling tank of any appropriate construction. Fig. 2 is a plan view of Fig. 1. Fig. 3 is a vertical section on the line 3-8 of Figs. 1 and 2, a portion of the casing being broken away to show the internal construction. Fig. 4 is a vertical section on the line 4-4 of Figs. 1 and 2. Fig. 5 is a detail showing partly in section on an enlarged scale a convenient construction of one of the cups of variable capacity, for measuring and distributing the chemicals. Fig. 6 is a plan view of Fig. 5. Fig. 7 is a view of a modified form. Fig. 8 is a section on the line 88 of Fig. 7 and looking in the direction of the arrows.

In the drawings a designates a filter or settling tank of any appropriate construction. Arranged above this settling tank is the measuring and distributing apparatus comprising essentially a vessel 1), of any shape and dimension, and adapted to contain t e chemical products which are to be added to the water. This vessel can be connected or be in communication with another vessel or reservoir, (not shown) in which the chemicals are mixed. In the drawings, the vessel 6 is Specification of Letters Patent.

shown square; this form however, may be varied at will, and may be of semi-cylindrical shape as shown in Fig. 8, rectangular, or of any other contour.

In the two end walls of the vessel 1), is

'journaled a shaft 0, to which is keyed or otherwise secured a water wheel or drum (1, having troughs or buckets, and a stirring device constituted by two cross frames 6, f, connected by rods or stirrers 9 see Figs. 1 and 2. To the arms of one of the cross frames 6, are attached, so as to be suspended therefrom, cups h, the construction and object of which will presently appear.

The drum d, provided with any desired number of compartments or buckets (P, as shown in Fig. 3 is arranged in a chamber i, separated from the vessel b, by a partition "6 To one side of this partition is secured a chute j, see Figs. 1, 2, 3 and 4, the lower part j of which is tapered, see Fig. 1. This chute communicates at its lower end through an opening 3' see Figs. 1, 3 and 4, in the partition i with the chamber i, containing the drum d.

The cups h, are attached to the arms e, or suspended therefrom, so as to, at all times, maintain a vertical position and to plunge successively in the solution contained in the vessel 6, as the cross frame 6 is rotated together with the shaft 0.

In the construction shown by way of example in the annexed drawings, these cups are arranged to freely turn about the axles h from which they are suspended at points above their center of gravity, within straps 7%, attached to the arms a, in any convenient manner. Each cup consists preferably as shown in Figs. 5 and 6, of a cylindrical body, having its internal surfaces partially screw threaded, so as to receive the screw threaded bottom or stopper h which on being screwed up or down, diminishes or augments as can easily be understood, the capacity of the cup h, and consequently the quantity of the chemicals scooped up by each cup, on its way through the vessel 1).

The upper portion of the chute j, carries an adjustable abutment, of any appropriate sha e, and consisting, as shown for example in ig. 4 of the drawings, of a hooped member or ta pet 7c the lower portion k of which is slotte and adapted to be secured by a screw on or the like, see Figs. 1, 2, 4, 7 and S, and adjustable at will, along the wall of the chute j, so as to project to any desired extent into the path of the cups h, carried along by the arms 0, during rotation.

The bearings n, n which support the shaft 0, in the walls of the vessel 1), are preferably open and the partition 1' has, for the passage of the shaftc, an opening or slot so arranged that the said shaft, together with the parts which it carries, namely the drum d, cups h, and the stirring device (1, f, g, may be easily with-drawn from the vessel 6, and from the compartment 2.

Arranged on the drum (Z, are stops 61 Fig. 3, into the path of which extends one of the ends of a lever q, pivotedat g? to a bracket r secured to or forming part of the vessel I). The other end of the lever Q is subjected to the influence of a spring-s, tending to draw the free end of the lever q, into the path of the stops (Z and adjustable by means of a screw t, or in any other convenient manner.

The operation of the apparatus is as follows. The water to be treatedis introduced through a pipe or conduit, 0, as shown in Fig. 3, into that compartment or bucket (1 of the drum cl, which at that moment happens to be opposite the opening of said-conduit 0. As this bucket d is gradually filledthe weight of the water contained therein forces the.

drum d, and shaft 0, to rotate until one of the stops d is caused to strike against the lever q. The drum d, is thereby arrested until a sufficient quantity of water is contained in the compartment al so as to over-come the resistance of the spring .9, and to rock the lever 9, against the action of said spring. This being done the drum. and shaft continue to rotate and on carrying with them the cups it, that cup which encounters the tappet k, is

' caused to be tilted upon striking the tappet 7c, and to discharge itscontents into the chute j, which in turn discharges the reagents carried by said bucket through the opening 3' into the chamber i, where they mix with the water discharged from the drum d, and pass through the port or outlet p, into the settling tank a. rotating, causes the cups h, to descend successively intothe solution of chemicals contained in the vessel 1), and to scoop up the latter, on their way to the tappet k, where they are emptied again into the chute j, as described. At the same time the stirrers g, traverse the solution contained in the vessel I), thus raking up or stirring the chemicals of which it is composed, and which are thus constantly and intermittently mixed witheach other.

It willbe understood that according to the proportion of chemicals desired to be added.

to the impure water, the capacity of the measuring cups h, with regard to that of the buckets d of. the drum 62, may be varied at will by adjusting the movable. bottoms h of the cups. Likewise, in adjusting if de- The drum (Z, in.

sired, the position of the tappetic, the extent of tilting of the cups it, can be so controlled as to add to the water according to the volume of 'each bucket d precisely the desired quantity of the re-agent.

In the modification shown in Figs. 7 and 8 I have shown the cup h arranged on the extreme end of the stirring device, so as to rotate concentrically about the circumference of the drum d and of the chamber 'i, and to discharge their contents directly into the compartment i or into the buckets d of the drum d. This is accomplished by the cups it coming into contact with an abutment 7c similar to 7c.

It will thus be seen that my device constitutes a measuring apparatus for the purifying of water, and provides a means whereby the water to be purified is first measured in the compartments (1, the filling of which is compelled by the controlling lever q; it also provides in the adjustable cups h a means for measuring quantities of chemicals, proportional. to the amounts of water delivered in the compartments (1 And that the operation of the cups h is rendered more certain by the adjustable stop or tappet 76 located on the chute 7', into which said cups discharge.

I do not limit myself to the details of construction as described and illustrated, since the latter may be varied without departing from the spirit of my invention.
